WINDOW.

Application led May 2, 1923. Serial No. 636,155.

To all whom it may comem-.

Be it known that we, JOHN POLACHEK, JULTUs JErsEN, and EDMUND PEREMI,citizens of the United States, and residents, respectively, of the cityof New York, borough of Manhattan, in the county and State lof New York;of the city of New York, borough of Brooklyn,l 1n the county of Kingsand State of New York; and of the city of New York, Elmhurst Manor, LongIsland, borough of Queens, in the county of Queens and State of NewYork, have invented a new and Improved Window, of which the following isa full, clear, and exact descri tion.

T is invention relates to improvements in windows and has particularreference to a metallic window construction. v

An object of the invention is to provide an improved window wherein thewindow frame and sashes are so constructed and interengaged that thesame will effectively prevent the ingress of air and dust into a roomwhen the sashes are in closin position.

Another object is to construct t e framesand sashes in such manner thatthe window may be readily and quickly assembled in operative positlon.

The above and other objects will a pear more clearly from thefollowing'detall description, when taken in connection with theaccompanyin drawings, which illustrate a preferred em odiment of theinventive idea.

In the drawin Figure 1 is a ront elevation of the window constructed inaccordance with'the invention; I

Figure 2 is a section substantially on the line 2-2 of Figure 1,-illustrating both sashes in cross section;

Figure 3 is a vertical transverse sectionv on the line 3-3 of Figure l;and

Figure 4 is a perspective view of one of the stiles of the sashes.

The window is made of any desirable material, such as steel or bronze,and the material is rolled or extruded to form the various arts of thewindow. The frame of the win ow comprises the side, to `and sillsections 5, 6 and 7, respectively. nasmuch as the side and top sectionsare identical in construction, a description of one will suiiice forboth and similar characters will be used to-designate like parts. Theside sections,

only one of which is illustrated in Figure 2, each comprises the outer,intermediate and inner portions 8, 9 and 10, respectively, theintermediate portion being secured along its longitudinal edges to theadjacent overlapping longitudinal edges of the outer and inner sectionsby means of suitable fasteners 11. Medially of its longitudinal edgesthe intermediate portion 9 is bent to provide a parting strip 12 and onopposite sides of said parting strip the portion 9 is further providedwith flanges 13 which combine with the sides of the parting strip 12 toform grooves 14 for a purpose which will presently appear. Thelongitudinal edges of the intermediate portion 9 are also bent to formanges 15 which cooperate with adjacent portions 16 and 17 of the outerand inner members 8 and 10 of the side section to form other grooves 18.

The sill section 7 is of channeled formation so as -to receive asuitable material 19 utilized to securely anchorsaid section in properposition-with respect to the sill of' the window opening. Intermediatethe edges of the section 7 the same is provided with an upwardlyprojecting portion 20 having the sides 21 and 22, the latter of whichcooperatesjwith a flange 23 to form a groove 24 for a purpose-which willappear in the course ofthe descri tion.

The window furt 1er comprises the upper and lower sashes 25 and 26 whichare practically identical in construction. The sashes 25 and 26 includeStiles, generally indicated by the numeral 27, the upper and lower rails28 and 29 and the meeting rails 30 and 31. The stiles 27 and the upperand lower rails 28 and 29 are substantially alike in construction andeach includes a web portion 32 having the ianges 33 extending from thelongitudinal edges thereof in the same direction and in parallelrelation. Adjacent one of the longitudinal edges of the web portion 32 athird flange 34 extends in the opposite direction from the flan es 33,but in parallel relation thereto and thls flange 34 is utilized insecuring the ane of glass in the window sash, as clearly illustrated inFigures 2 and 3. The flanges'33 of the stiles 27 and the same flanges ofthe top rail 28 of the upper sash are en ageable in the rooves 14 and 18and comine with the si e and top sections of the frame to form the airchambers 35. By the provision of the plurality of points of contact andinterengagement between the frame and the sashes and the formation ofthe air chambers, it will be obvious that the construction willeffectively prevent the ingress of air or dirt into the interior ofa-room when the sashes are in closing position. The flanges 33 of thebottom rail 29 are of different widths and when the lower sash is inclosing position the outer flange overlaps the side 21 of the portion 20of the sill section, while the inner flange engages in the groove 24formed by the side 22 and flange 23, thus further providing an effectivemeans for preventing air and dust entering a room; The bottom rail 29combines with the portion 20 of the sill section to form an air chamber36 which communicates with the chambers 35. The meeting rails 30 and 31are provided along their adjacent edges with flanges 37 and 38,respectively, which overlap as clearly illustrated in Figure 3, when thesashes are in closing position.

Disposed on each side of the window frame and extending partially overthe top thereof are casings 39 in which the parting strips 40 aredisposed for dividing the casings into compartments for receiving theusual counterweights 41 for the sashes. The intermediate portions 9 ofthe side sections of the frame may be provided, if desired, with rubberbumpers 42 attached to plates 43 and against which the lower sash 26 mayengage to prevent noise when opening the window. The intermediateportions 9 may be removed by looseninglthe screws 11 so that access maybe had to the interior of the casings 39 for the purpose of repairing orreplacing the counterweights or their associated parts. l

The lower sash 26 may be provided with an operating handle 44 tofacilitate the raising and lowering of the sash. The meeting rails 30and 31 are locked together by a locking device 45 of any desiredconstruction and in addition to this lookin device the lower sash 26 mayalso be provi ed with a suitable lock 46 in the form of a spring pressedbolt carried by the inner section 10, as shown in Figure 2.

What is claimed is:

l. In a window construction, a. Window frame having side, top and sillsections, said side and top sections each including inner, intermediateand outer members, said intermediate members being formed with a partingstrip and flanges arranged on each side of said strip, certain of saidflanges combining with said parting strip to formY grooves and others ofthe flanges combining with the inner andv outer` sections to form othergrooves, said sill section being provided with an upwardly extendingportion and a flange adjacent said portion to form a groove, and sashesmounted in said frame and including flanges engageable in the grooves insaid side, top and sill sections when the sashes are in closingposition.

2. vIn a window construction, a window frame having side, top and sillsections, said side and top sections each including inner, intermediateand outer members, said intermediate members being formed with a partingstrip and flanges arranged on each side of said strip, certain of saidflanges combining with said parting strip to form grooves and others ofthe flanges combining with the inner and outer sections to form othergrooves, said sill section being provided with an upwardly extendingportion and a flange adjacent said portion to form a roove, and sashesmounted in said frame an including flanges engageable in the grooves insaid side, top and sill sections when the sashes are in closingposition, the flanges of said sashes and sections cooperating to formair chambers.

3. In a window construction, a window frame formed with a side section,said side section comprising inner, intermediate and outer members, saidinner and outer members being formed with means adapted to interlockwith a wall, an upstanding portion ladapted to fit against the windowsash and an inwardly extending portion adapted to overla part of theintermediate member, said intermediate member being formed with a.section substantially Ushaped in cross section at the center acting as aparting strip, a pair of flanges spaced a short distance from saidvparting stri whereby sash receiving grooves are provi ed, an upstandingflange at each edge of the intermediate member co-acting wlth the innerahd outer members for forming sash receiving grooves,l and a air. offlanges on the side of the interme iate member opposite the partingstrip adapted to engage said inner and outer members along their inneredges, and means extending through the intermediate member for rigidlysecuring the same to said inner and outer members.
